King Size Bed Frames

A king size mattress measures 150 cm by 200 cm. In the imperial naming the trade still uses, that is 5ft. It is the first UK size to gain length as well as width: 10 cm longer than a double and 15 cm wider. The extra length is the reason it is often chosen for a taller sleeper, and it is also why king size bedding is not interchangeable with the smaller sizes. The bed frames here come from several ranges, and each listing below shows its king size price. This is not the entry size on most of these frames — most cost more here than in their smallest size, so the prices below are the ones that apply to this size rather than a starting figure.

Will one fit your room?

Every frame here holds the same 150 cm mattress, but the frames themselves differ in width. Plan with the frame dimension on each product page. Measure your wall and subtract the frame width given on the product page. Do the same for depth against the 200 cm length — which is longer than the smaller sizes, and catches people out in a short room.

King Size mattresses and bedding

Any king size mattress fits any of these frames. That is what the size name guarantees: 150 × 200 cm is a standard, not a description. Bedding is the exception people forget. King Size sheets and duvets are cut for the longer 200 cm mattress, so bedding from a smaller bed will not fit even though it may look close on the shelf. Depth is the one dimension that is not standardised. It changes how high the finished bed sits and how the mattress looks against the frame.

What the choice comes down to

Every frame here is the same size, so the decision is about everything else: fabric, wood, crushed velvet, linen and velvet, among others. Some frames on this page belong to collections with matching bedroom furniture, which is worth knowing before you choose on looks alone.

Common questions

What size is a king size bed?

The mattress is 150 cm by 200 cm — 5ft. The frame around it is larger and varies by design; each product page gives its own width.

Do these king size beds include a mattress?

No. Frames are sold on their own and mattresses are bought separately.

Will my existing bedding fit a king size bed?

Not if it came from a smaller bed. This size is 200 cm long rather than 190 cm, so fitted sheets and duvets are cut differently.

How is it delivered?

Flat-packed, with larger frames in more than one carton. Each page lists its carton count and heaviest carton weight.
